Abstract
L'invention concerne un procédé de préparation du 1,2-dichloréthane par oxychloration de l'éthylène à l'aide de gaz chlorhydrique et d'un gaz contenant de l'oxygène moléculaire en phase gazeuse, à température élevée et en présence d'un catalyseur à lit fluidisé au chlorure de cuivre-II sur un support, dans lequel on refroidit sous pression les gaz de réaction en deux stades de condensation, on évacue ensuite le 1,2-dichloréthane condensé et on recycle la majeure partie des gaz de départ non convertis et des gaz inertes. Le procédé selon l'invention est plus particulièrement caractérisé en ce que, dans un troisième stade de condensation, on refroidit les gaz de réaction à une température comprise entre 5 et 18 degrés C dans une mesure juste suffisante pour retenir 0,5 à 3,0 % en volume de 1,2-dichloréthane et on mélange directement, en amont du réacteur, le gaz de recyclage avec la quantité d'oxygène pur nécessaire pour remplacer l'oxygène consommé et retablir une teneur en oxygène de 12 à 25 % en volume.The invention relates to a process for the preparation of 1,2-dichloroethane by oxychlorination of ethylene using hydrogen chloride gas and a gas containing molecular oxygen in the gas phase, at elevated temperature and in the presence of. a copper-II chloride fluidized bed catalyst on a support, in which the reaction gases are cooled under pressure in two stages of condensation, the condensed 1,2-dichloroethane is then discharged and most of the gases are recycled. starting unconverted and inert gases. The process according to the invention is more particularly characterized in that, in a third condensation stage, the reaction gases are cooled to a temperature of between 5 and 18 degrees C to an extent just sufficient to retain 0.5 to 3, 0% by volume of 1,2-dichloroethane and the recycle gas is mixed directly, upstream of the reactor, with the quantity of pure oxygen necessary to replace the oxygen consumed and restore an oxygen content of 12 to 25% in volume.
